ESTABLISHING SURFACE PARAMETERS WHILE PRINTING A THREE-DIMENSIONAL OBJECT FROM A DIGITAL MODEL

An apparatus and system for applying surface parameter(s) to a three-dimensional (3D) printer object while the 3D printer object is being printed from a digital model. The surface parameter(s) includes a surface texture of a reference surface. The reference surface is scanned by a sensor to detect the surface parameter(s). The detected surface parameter(s) are received by the 3D printer for application to the 3D printer object. The surface texture is applied by a 3D printer to the 3D printer object while printing the 3D printer object based on the 3D digital model.

Apparatus and methods for controlling pressure on a thermoforming assistive device

Apparatus and methods of forming sheets of material are disclosed. Profile plates may be placed atop the sheets. Tabs attached to clamp frames may apply uniform pressure on the perimeters of the profile plates during the formation process.

Abuse-proofed dosage form

The invention relates to a dosage form that is thermoformed without discoloration and is safeguarded from abuse, comprising at least one synthetic or natural polymer having a breaking strength of at least 500 N in addition to one or more active substances that could be subject to abuse. The invention also relates to a corresponding method for producing said dosage form.

System and method for test pattern formation during three-dimensional object printing

A three-dimensional object printer ejects drops of a build material from a plurality of ejectors in a first printhead to form an object on a first region of a member and ejects drops of a support material from a plurality of ejectors in a second printhead to support the object on the first region of the member. The second printhead ejects drops of the support material onto a second region of the member that is separate from the first region to form a substrate layer. The first printhead ejects drops of the build material onto the substrate layer to form a printed test pattern. An image sensor generates image data of the printed test pattern to identify an inoperable ejector in the first printhead.

Printing-height increasable three-dimensional printer

A printing-height increasable three-dimensional printer includes a base, an elevating shaft, an elevating platform, a first driving module, a working platform, a printing nozzle, and a second driving module. The elevating shaft is connected to the base. The elevating platform is slidably connected to the base. The first driving module is configured to drive the elevating shaft to make the base move along a direction, and is configured to drive the elevating platform to reversely move relative to the base along the direction. The working platform is slidably connected to the elevating platform. The printing nozzle is connected to the base and is configured to print on the working platform. The second driving module is configured to drive the working platform to move between the printing nozzle and the elevating platform.

Wrinkled surfaces with tunable hierarchy and methods for the preparation thereof

This invention relates to the low-cost manufacture of a tunable physical topographic pattern and more particularly to the manufacture of micro and nano scale hierarchical periodic wrinkle patterns that are generated upon compression of supported thin films. Disclosed herein is (i) a composite material with tunable hierarchical wrinkle patterns, wherein the composite material comprises a stretched and pre-patterned base layer and a thin film that is conformally attached to the pre-patterned surface of the base layer, (ii) a method of fabricating the pre-patterned base via pattern replication, and (iii) a method of fabricating tunable hierarchical wrinkle patterns, wherein the pattern can be deterministically switched across the hierarchical and non-hierarchical states via strain control.

METHOD OF MAKING PARTICLES HAVING A RIDGE PORTION FOR USE AS PROPPANT

A method for forming particles having a ridge portion includes inducing flow of a slurry of particles and a reactant through one or more orifices, detaching an amount of the slurry from the slurry flow following exit from the one or more orifices, the detached amount forming a slurry body, forming the slurry body into a particle shape, contacting the particle shaped slurry body with a coagulation solution to form a stabilized particle having the ridge portion, and drying and/or sintering the particle having the ridge portion.
